Fourses Automatic Patch

The patch for the previous post uses my Big Euro Box.  There are two parts:  the control patch and the audio patch.  Pardon the poor sketches.

Control Patch

The control patch generates two sets of controls:  six stepped controls from six sample & holds, and six envelopes from the Just Friends module.  These can be applied to any audio patch.

Control Patch

Sampling & Holding

Tromsø is a combination of three basic utility modules: Triangle VCO/LFO, Comparator (SQ), and Sample & Hold.  I used three Tromsø.  In the block diagram the lower blocks represent the LFO with FM input, TRI and SQ outputs.  The middle block represents the sample & hold in Tromsø.  The output of each S&H is patched to the FM of the same Tromsø.  Three more sample & holds, 2hp modules, are shown in the top row of blocks.  These are sampling the TRI outputs and sending them over to the inputs of the other Tromsø sample & holds, in a cycle.  All Tromsø are set to LFO range.

Triggering

The SQ wave outputs of the three Tromsø patch through clock dividers to the three logic inputs of the Klavis Logica Gater.  Logica Gater output clocks the Pithoprakta probabilistic pulse generator, which in turn provides six triggers for Just Friends in envelope generator mode.  Just Friends gets some FM from the third stepped output.  The same triggers clock the six sample & holds.

Audio Patch

Ieaskul F. Mobenthey Fourses is made up of four interacting VCOs.  Two of Fourses Bounds inputs are patched from two stepped controls in a manner as to separate these two from the other oscillators and make them more tonal.  The Fourses outputs are patched to the dual inputs of two Make Noise LxD low pass gates.  LxD CV inputs come from four envelopes of Just Friends.  LxD outputs are mixed in the SSF Mixmode with its saturator enabled.  The signal then passes through Dave Smith Instrument DSM03 Feedback and then through a Disting MKIII in Clocked Ping Pong Delay mode.  DSM03 Timing is modulated by a stepped output from control, passed through a Mini-Slew for fixed slewing.  Disting is clocked from the Ultra Random Analog (just the clock is used), which is modulated by one of the stepped outputs from controls.

Audio Patch

Example Recording

After the patch is established, a tweaking and tuning phase begins, before a hands-off recording of automatic music is made.  Much variety is to be had, and here it is only my judgment as to what to record.  In the following, notice how some chord progressions spontaneously develop and then recapitulate.
